To all whmn it may concern;

Beit known that L DAVI D HENRY MAR- srIAIJL, a citizen of'the UnitedStates,'resid ing at KansasCity, in'the county of J ackso'n and State bfMissouri, have inventeda new and useful Automatic Car Annun'ciat'or, ofwhich the following is a specification:

My invention relatesto certain new and useful improvements in carannunciators, and has for its object to providean'annum ciator that willindicate the street or'station as approachedautomatically.

Another objectof my invention is to provide'an annunciator that isespecially adapt ed to be used on cars operated by electricity.

A further object of the invention is to pro vide an alarm'in connectionwith the anm'mciator, so that the passengers will be notified when thename of a streetappears in the annunciator. l

I/Vith these objects in view my invention consists of the novel featuresof construction and "combination of parts, hereinafter' 'described, andpointed out in the claims.

In the drawings forming a part of the specification, Figure '1 is asectional view through a car, showing the annunc'iator 'in lace. Fig. 2is a front view ofthe annunciator with the front removed. Fig. 3 isaside view of the annunciator with 'one side removed; Fig. 4 is a frontview of the guide way carrying the block. Fig.5 is a sectional viewtaken on the line 5 5 of Fig. 4. Fig. 6 is a transverse section of theguideway, showing the supporting-frame partly broken away. Fig. 7 is adetail view of my improved trolley and its connections, and Fig; 8 isadetail view of the trolley.

Referring to the drawings,'A indicates the boX inc-losing theannunciator, whichis provided'with the ordinary sight-opening A,arranged in the front and being protected by a pane of glass A -Securedin the casings are the uprights B and B, connected together by the barsB and the bolts B Mountedin the uprights B and B are the shafts C and C,provided with rollers O and C carrying the belt C, which passes over thebars B? and having the names of the streets'o'r stations printedthereon. The ends of the shafts eX- tend through the uprights B and areprovided with gear-wheels C and C meshing with a large gear-wheel D,journaled on the shaft D, secured in the uprights B. The

Specification of Letters Patent.

outer face of the wheel D is provided with outwardly-projecting lugs Dfor the purpose hereinafter described: Extending out-fromtl1e"uprights"B" are bolts E, carrying the frame j E, which is providedwith the guidew'ay F, slida'bly mounted on the-upperand lowerbars'oftheframe'E. The guideway F consists of a flat plate'F, having itsends F bent'in'the form' ofa tube fitting over the bars of theframe E;as shown in Fig. 5. The sides F adjacent the ends F are cut inwardly atand are bent upwardly at F and inwardly at F plate is provided with an"outwardly-projecting wrist-pin F carrying the shifting lever F sothatt'he plate F can'beadjusted to either end ofthe frame E desired.Sliding in the guideway Fis 'a block G, havingan arm G extendingtherefrom and outwardlyextendi ng shoulders'G providedwith' grooves Gfitting over the inwardly projecting sides F of' the plate F. Theblock'G'is provided with an opening G in 'which *is mounted a pivotedpawl G adaptedtoengage'the lugs D of the gearwheel'D on its upwardstroke and revolve the'said wheels.

Securedto the bolts B is a bracket II, carrying a double"solenoid magnetI, having a double cor'eor armature I" cooperating there with, to whichis pivotally connected a rod I the other end of which ispivotallyconnected to the arm G of'the block G. The magnet I and armature I areprovided with contact-plates "I which are connected by wires I to thebattery J and bell K, so that when the armatures are drawn up thecircuit bell willring, notifying'the passengers that a street or stationis near. This current for exciting the solenoidmay be derived from anymeans desired;'but I preferably employ a contact 'shoe L, carried by thetrolley-wire M, having a horizontal portion L, adapted to engage thecontact-piece N, carried by the fork N of the trolley-pole N. Connectedto the co'ntact-piece N is a conductor 0, which passes down thetrolley-pole N through the solenoid and is'grounded through the wheeland track. I

A contact-shoe L'is placed'on the trolley M, near each of the streets orstations that are printed on the belt 0". As the car comes along thecontact-piece N comes in contact will be'compl'eted through the'platesand the v The operation of the device is as follows:

with the shoe L, and the current is carried down through the conductorand through the solenoid I to the ground. The solenoid, being excited bythe current, pulls upon the armatures I, which raise the rod 1 and withit the block G, carrying the pawl G whichblock G on its upward stroke,will revolve the gear-wheel D in an opposite direction.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination in a carannunciator, of rollers carrying a belt,gear-wheels for operating said rollers, a gear-wheel provided with lugsand meshing with the gear-wheels, a guideway slidably mounted on aframe, a block sliding in said guideway, a pawl carried by said block,and means for operating the said block, for the purpose described.

2. The combination in a car-annunciator of a casing having shaftsmounted therein, carryingrollers, a belt mounted on said rollers,gear-wheels carried by said shafts, a gearwheel provided with lugs andmeshing with said gear-wheels, a frame arranged adjacent saidgear-wheel, a plate slidably mounted on said frame, avertically-reciprocating block mounted on said plate provided with apawl and a lever connected to said plate, for the purpose described.

3. The combination in a car-annunciator, of rollers carrying a belt,gear-wheels carried by said rollers a gear-wheel meshing with saidgear-wheels, a frame arranged to one side of said gear-wheel, a plateslidably mounted on said frame, a block slidably mounted on said plate,carrying a pivoted pawl adapted to engage lugs arranged on saidgear-wheel, means for operating said block together with means forshifting said plate, for the purpose described.

4. The combination with a casing provided with a sight-opening,'ofaframe arranged in said casing, rollers arranged in said frame above andbelow said sight-opening carrying a belt, gear-wheels arranged on theend of said rollers, outside the frame, a gearwheel provided withoutwardly-projecting lugs mounted on said frame meshing with saidgear-wheels, a frame arranged to one side of said gear-wheel, a plateslidably ranged in said casing above said frame connected to said block,for the purpose described.
